A free shape total reflection-long capillary cell was applied as the optical cell for highly sensitive absorption spectrometry(10~4 times enhacement in absorbance). High transmission was attained by applying the transparent solvents of high refractive indices to the cell. Optical pathways (meridional ray and helical ray)inside the LCC was important: Since multi-reflection of source light occurs inside the capillary, the light-path length extends several times more than the apparent cell length.

A free shape total reflection-long capillary cell was applied as the optical cell for highly sensitive absorption spectrometry(10~4 times enhacement in absorbance). High transmission was attained by applying the transparent solvents of high refractive indices to the cell. Optical pathways (meridional ray and helical ray)inside the LCC was important: Since multi-reflection of source light occurs inside the capillary, the light-path length extends several times more than the apparent cell length. Effects of the multi-reflection was discussed in terms of elongation of optical pathways and curveture in the calibration curve obtained by the LCC. Theoretical equations of absorbance for LCC to the Lambert-Beer's law was gived. Absorbance using theoretical equations is calculated by micro-computer.

本文应用光学的Snell折射定律,使用以二硫化碳为主的高折射率的液体做为混合溶剂,实现了入射光在吸收管中的全反射,制成了类似于液体光导纤维的光导型全反射长光路毛细吸收管(TR-LCC)。比普通的吸光光度法的测定灵敏度提高4个数量级以上。并进一步探讨了在TR-LCC中存在的两种不同形式的光通路——子午光线和螺旋光路,以及对测定灵敏度的影响。对决定吸光度的各种因素进行了理论的探讨,得出了在全反射长光路毛细吸收管吸光光度法中吸光度的理论计算式——对朗伯-比尔定律的补正式。同时运用微型电子计算机进行了计算解析,确定了由于吸收管壁的多重反射对于测定吸光度的增幅效果,以及其工作曲线是一条弯曲的曲线,偏离理想状态下的朗伯-比尔定律。

In this paper the coordinates of two virtual sources and the distance betwween them in biprism interference are derived. The reason that the measured wavelength by imagining through the converging lens (once or twice) is bigger than the reality is discussed. Because the monocentric bundle from the slit are turned into astigmatic bundle after the refraction of the biprism, the measured distance between the virtual sources is the distance of the meridional rays of them. In order to rebate system deviations...

In this paper the coordinates of two virtual sources and the distance betwween them in biprism interference are derived. The reason that the measured wavelength by imagining through the converging lens (once or twice) is bigger than the reality is discussed. Because the monocentric bundle from the slit are turned into astigmatic bundle after the refraction of the biprism, the measured distance between the virtual sources is the distance of the meridional rays of them. In order to rebate system deviations and gain better results, the way of shifting the biprism should be adopted.

计算出了两虚光源的坐标位置。分析讨论了在测光波长的实验中,用会聚透镜成像法得到的实验结果偏大的原因,是由于狭缝发出的单心性光束经双棱镜折射后,变成了像散性光束,测到的两虚光源的像之间的距离实际上是两虚光源的子午焦线之间的距离。为了减小系统误差,应该采用双棱镜移位法。

The integral expression of absorbance presented by Wei Lei et al. for meridional ray TR-LCC was revised and simplified, and the analytical expression was obtained. According to the analytical expression, dependences of absorbance on parameters such as the product of molar extinction coefficient and molar concentration of the solute, the length of OWGC and the linear apparent scattering coefficient of the solvent were calculated by microcomputer. The calculated results indicate that there are very good...

The integral expression of absorbance presented by Wei Lei et al. for meridional ray TR-LCC was revised and simplified, and the analytical expression was obtained. According to the analytical expression, dependences of absorbance on parameters such as the product of molar extinction coefficient and molar concentration of the solute, the length of OWGC and the linear apparent scattering coefficient of the solvent were calculated by microcomputer. The calculated results indicate that there are very good linear dependences of absorbance on the concentration of the solute and the length of the OWGC. That is, the Lambert-Beer's law is still applicable for this kind of OWGC, and the variation of linear apparent scattering coefficient has no effect on the above linear dependences.

本文对文献[1]的全反射长毛细管吸收池中按子午光线反射导光时的吸光度积分计算式进行了修正简化,推导出其解析表达式,并据此式用微机计算了吸光度A对摩尔吸光系数和浓度的乘积e·c、吸收池的长度,和溶剂的表观散射系数β等参数的依赖关系。结果表明,A与ε·c(即与C)和,成很好的线性关系,即仍符合朗伯-比耳定律,而β值的变化对上述线性关系没有影响。
